You're welcome. It's the kind of thing where you have to have been
bitten by it yourself in order to readily identify the problem. About a
year ago, I was bouncing mail to a couple sites, and eventually I
learned about ECN. Actually, ECN is a good thing, though disabling it is
justifiable if you never want to diagnose this problem again.
In the kernel config, look in Networking Options->IP: TCP Explicit
Congestion Notfication. It's also "CONFIG_INET_ECN=y" in your .config,
so disabling it in either place will help. You could also wrap the
script that contacts ananova in call to disable and re-enable ecn if you
wanted to leave it in the kernel.
